Prescription drugs

Quick find

Note: To make sure you pay the right amount for your prescriptions, always show your UMP ID card first. If you have a prescription drug discount card, show that card second to see if you can get a discount on prescriptions UMP does not cover.

Prescription price check tool or UMP Preferred Drug List?

Use the prescription price check tool if you are looking mostly for how much your drug will cost. To get information specific to your account, log in to your pharmacy account and use the tool.

The UMP Preferred Drug List  is a better bet if you are looking for the following:

Note: The UMP Preferred Drug List is updated often. Changes are posted online at least once a month. However, a drug may change tiers at any time, especially when a generic equivalent becomes available.

You can search the UMP Preferred Drug List by drug name or by drug class (for example, cardiovascular drugs). If you know of one particular drug, you can search for it by name and note the drug class; then you can find similar drugs by searching for that class.

Why does UMP cover or not cover different drugs?

To find the criteria a drug must meet to be covered by UMP, and covered exceptions, read the "Guidelines for drugs UMP covers" section in your PSHVN or UW Medicine ACN 2018 certificate of coverage. This section also explains which products are covered as preventive (including tobacco cessation products and some contraceptive drugs or supplies) and also contains the guidelines for drugs UMP does not cover.
